Interplay of orbital magnetic moment and chiral magnetic effect in Shubnikov–de Haas quantum oscillations

نویسندگان

چکیده

Emergent Lorentz symmetry and chiral anomaly are well known to play an essential role in anomalous transport phenomena of Weyl metals. In particular, the former causes a Berry-curvature induced orbital magnetic moment modify group velocity electrons, latter results effect be responsible for "dissipationless" longitudinal current channel bulk. this study, we verify that intertwined these two effects can measured Shubnikov-de Haas (SdH) quantum oscillations, where double-peak structure SdH oscillation appears cause kink Landau fan diagram. We examine three different cases which cover all possible experimental situations external electric/magnetic fields identify condition existence structure. claim interplay oscillations is interesting feature metal state.

Shubnikov-de Haas oscillations in high mobility GaAs quantum wells in tilted magnetic fields

We report on quantum magneto-oscillations in a high mobility GaAs/AlGaAs quantum well at very high (≥ 87◦) tilt angles. Unlike previous studies, we find that the spin and cyclotron splittings become equal over a continuous range of angles, but only near certain, angle-dependent filling factors. At high enough tilt angles, Shubnikov-de Haas oscillations reveal a prominent beating pattern, indica...

Magnetic quantum oscillations in nanowires.

Analytical expressions for the magnetization and the longitudinal conductivity of nanowires are derived in a magnetic field, B. We show that the interplay between size and magnetic field energy-level quantizations manifests itself through novel magnetic quantum oscillations in metallic nanowires. There are three characteristic frequencies of de Haas-van Alphen (dHvA) and Shubnikov-de Haas (SdH)...
